Cone type is because the yarns are arranged at a tighter interval than the cork form, so that the water repellent alone cannot penetrate all the yarns evenly. However, in the case of water repellent in the form of a cone, since the water-repellent yarn is already arranged in a cone form, the yarn is less entangled when entering the knitting.

In the case of acetic acid, less than 0.3 parts by weight is required to remove residual alkali from the product. However, when more than 1 part by weight of acetic acid is contained, the acid content may increase, which may damage the yarn.

  • the 'fit' indicates the result value of level 4 or higher, 'good' 'Indicates a level 3 result, and a non-conformity indicates a level 2 or less result.
  • the softener is preferably added after the water repellent is provided, and the softener may affect the water repellent effect, so that the softener is not used if the softening of the yarn can be maintained without the addition of the softener.
  • Knitting yarn was used as the yarn made of 70% by weight of wool and 30% by weight of nylon, and 1kg of the knitting yarn was provided to the container in the form of a cone. Knitting yarn provided in the container went through a washing step to remove the foreign matter by spraying a soapy water having a temperature of 50 °C for 30 minutes to the yarn at a pressure of about 0.5kgf / cm2. Thereafter, the water-repellent solution was sprayed on the washed yarn at a temperature of 40 ° C. for about 30 minutes at a pressure of about 2 kgf / cm 2 to coat the water repellent on the knitted yarn.
  • the water repellent solution is composed of 10 kg of water, 50 g of water repellent, 3 g of penetrant, and 5 g of acetic acid, and the water repellent used JC-9000 of Venesco, and the penetrant used JW-1000 of Venesco.
